net: stmmac: Rework coalesce timer and fix multi-queue races

This follows David Miller advice and tries to fix coalesce timer in multi-queue scenarios. We are now using per-queue coalesce values and per-queue TX timer. Coalesce timer default values was changed to 1ms and the coalesce frames to 25. Tested in B2B setup between XGMAC2 and GMAC5.
